Patent CA-2069641-C (CA)
Inventor: FISHER JERRY D
IPC: B08B3/08
Filed: 1991-10-10
Granted: 1998-03-31
Abstract: A method for maintaining a flammable solvent in a nonflammable environment involves covering the flammable solvent with a nonflammable vapor blanket provided by a nonflammable solvent, such that vapors from the flammable and nonflammable solvents form a nonflammable gaseous mixture in the blanket.  Such a method is used in removal of both oil-based and polar contaminants to control the flammability potential of an alcohol solvent.  An aparatus (10) for cleaning articles using fluorocarbon and alcohol solvents includes a chamber (20) having a plurality of compartments (26, 28, 30) for containing the solvents and a bounded vapor space (24).  At least one of the compartments contains liquid fluorocarbon and at least one other will contain liquid alcohol.  The solvents volatilize into the bounded vapor space (24) to provide a nonflammable vapor blanket over the alcohol-containing compartment (28).  Volatilized alcohol is mixed with the volatilized fluorocarbon to form a nonflammable mixture which is purified and separated, and the recovered fluorocarbon can be reused in subsequent cleaning operations.

Title: Method for synchronizing tooling in a die-cutting machine for generating die-cut blanks
Inventor: MORRISON RICHARD E
IPC: B26D7/26
Filed: 1994-02-23
Granted: 1997-12-09
Abstract: A method for Aligning the process tools of a typical box blank die-cutting machine is provided herein. The method contemplates the use of alignment openings on the surfaces of male and female tools corresponding to a cut through-hole on a test sheet. As the test sheet is urged through the procedure, a series of alignment cylinders is used to insure that each of the male and female tools and test sheet are aligned by having the alignment cylinders fall cleanly through the various alignment openings and the through-hole. Once the tools at each position of the procedure are aligned, alignment screws and alignment members on the machine frame serve to fix the position of the tools relative to the position of the sheets to be die-cut, stripped and blanked. Accordingly, the method contemplates alignment and set-up of the machine based upon the urged position of the sheets to be etched and cut.

Abstract: A bill acceptor door is pivotally mounted to a cabinet access door of a cabinet by a hinge arrangement that facilitates assembly, but which provides secure retention of the bill acceptor door. In particular, the hinge arrangement includes a hinge bracket defining a pair of slots, and the bill acceptor door includes a housing defining a pair of slot engaging pivot pins. The housing is configured to securely receive a bill acceptor and a bill collector cartridge, but only after the bill acceptor door is mounted on the cabinet.

Granted: 1999-02-09
Abstract: A biosensing meter (50) receives a biomedical sample strip (10) which includes electrically isolated excitation (14) and sense (12) electrodes or, alternatively, a check strip. The biosensing meter includes first and second contacts (C, D) that are connected by a sense electrode upon insertion of a sample strip. An operational amplifier circuit has first and second inputs respectively connected to the first contact and a reference potential, the first input manifesting the reference potential as a result of a feedback within the operational amplifier. A processor (60) is coupled to the second contact and determines the presence of the reference potential at the second contact when an inserted sense electrode connects the first and second contacts. The processor also distinguishes between sample and check strips and tests for a proper impedance between the sense and excitation electrodes of a sample strip, thus enabling operation of the biosensing meter upon sample strip dosing.

Title: Method and equipment for the production of shaft information data of a lift shaft
Inventor: GERSTENKORN BERNHARD
IPC: B66B3/02
Filed: 1995-12-14
Granted: 2006-05-23
Abstract: In the case of this lift shaft (1), a reflector (2) with a code (3) is arranged in the region of a stopping place. The code (3) displays two identical tracks (4, 5). The level of the stopping place is illustrated by the broken line (H O), to which the code (3) is symmetrical. A moving-in region (B E), in which the bridging-over of door contacts is permitted, lies half above and half below the level line (H O). A resetting region (B N), in which a resetting of a lift cage (6) lowering due to cable expansion is permitted with bridged-over door contacts when the doors are open, lies half above and half below the level line (H O). The code (3) of the tracks (4, 5) is detected and evaluated by a 2-channel evaluating equipment (7) arranged at the lift cage (6). Transmitters (8, 9) of the evaluating equipment (7) illuminate the tracks (4, 5) of the reflector (2). The illuminated surf aces of the tracks (4, 5) are imaged onto charge-coupled device sensors (10, 11) of the evaluating unit (7) and detected by means of a pattern recognition logic system. The preparation of the images into the information, which serves for the lift control, takes place by means of a computing equipment.
